' TRACTOR.

To all whom it may concern: I

Be it known that I, Join: B. Corraon, a citizen of the United States,residing at 444 West Fifth street,.Eugene, in the county of Lane andState of Oregon, have invented certain new anduseful Improvements inTractors, of which the following is a specification.

This invention relates to motor driven apparatus and more particularlyto motor plows, and hasfor its objectto provide a motor plow includingdriving motors and traction Wheels arranged for individual connectionwith .the driving shaft so that one wheel may be disconnected to turnthe ma chine in one direction or the other'wheel may be disconnected toturn the machine in the-opposite direction, a steering caster beingprovided and arranged to'facilitate the just described operation.

Another object is to provide a structure in which the frame will soarranged that the'furrow side will be raised or lowered as desired.

Other objects and advantages willbe apparent from the followingdescription and it will be understood that changes-in the specificstructure shown and described may. be made within the scope of theclaims, and that anysuitable materials may be used without departingfrom the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a side elevation of the present plow, Fig. 2 is a top plan,Fig. 3 is a transverse section taken on the-line 3-3 of Fig. 1, throughthe driving shaft showing the means for connecting the wheels with theshaft, Fig. 4: is a verticalsection through the foot trip mechanism forreleasing the steering caster, Fig. 5. is a de tailed view. in sectionof the caster mount:

Referring now to the drawings, there is shown a plow comprising ahorizontally extending frame 6 including parallel side members 7 and 8.The side member 7 ex-. tends rearwardly beyondlthe member 8, andthemember '8 has a transverse member 9 secured to its rearward end and alsosecured" r fi pn of sa n Patented'Jan. 31, 1911. I Application filed my10, 1909. Serial No. 506,878.

andthis bar 12 hasthe end-ofa steering chain 13 secured thereto, thissteering chain being engaged around a'drum 1 carriedby' a steeringshaft- 15 extending vertically.

from the frame 6 having a steering wheel 16 at its upper end locatedwithin reach of the occupant of a seat-17. mounted upon the frame. Adownwardly-and rearwardly extending bracket 18 is secured to the member7 7 and at its lower end ositioned beneath the opening 10 and providedwith a passage 19 in alinement with the opening 10. This passage 19receives the stem 20 of a wheel yoke 21 in which there is journaled acaster wheel 22.

' The stein 20 has an enlarged head 23 secured upon its upper'end, whichhead prevents disengagement of the stem from the bracket 18, and isprovided upon its top with clutch fingers 24. 1 Ash ing clutch member 25is mounted upon the lower portion of the shaft 11 for movement into andout. of engagement with the clutch fingers 24, and a yoke 26 isconnected with, the clutch member 25 for. rotation of the; clutch memberwith respect thereto, the yoke having a' link 27 pivoted thereto .andpivoted to a bell crank lever 28 mounted upon the frame beam 7, thisbell crank lever being connected with a foot trip member 29 foroperation by the foot of an occupant of the seat 17 to raise the clutchmember 25'ahd thus release thocaster wheel 22 topermit' free swingingthereof. When the arts are in operative coengagement, it wi I. be

understood. that thewheel may be turnedby means of the steering wheel 16to properly guide the machine.

Depending straps 30 are carried by'the' frame 6, and these strapscarryplows 31 at their lower ends. At the forward portion of the frame6, there is mounted a transverse shaft 32. There are two parallelgasolene motors 33 mounted on the frame. As show-m1 suitable water andfuel supply tanks 34: and 35 are provided for" the motors The motors areconnected with a "common power shaft 36, having a flywheel 37 at one endand carrying sprocket wheels 38 with which there are engaged .chains3!), extending downwardly. Friction clutch members 40 are mounted uponthe shaft 32 and have conical recesses in their outer ends arranged toreceive conical inwardly directed projections 41 carried by the tractionwheels 42 which are loosely'mounted upon' the outer ends of the shaft32. The clutch members 40 have sprockets '43 which receive the chains'39, and 'yokes 44 have fingers 45 which are engaged in peripheralgrooves 46 of the clutch niem bers 4% these yokes having stems 47 whichare pivote as shown ,at 48 for movement of the clutch members into andout of engagement with theI'projections 41. Hand levers 49ers providedfor individual operation of these.

clutch members, so that the wheels 42 may be individually connected withthe driving mechanism to turn the machine in either direction ashereinbefore stated.

As will be' understood, when the plow is 'one end-of'the shaft 36 forthe transmission of power to other mechanisms.

What is claimed is: v

1. In a power driven apparatus, the combination with a frame includingtwo paralvlel members, one of said members extending 3' description. Abelt pulley 50 is carried by rearwardly beyond the other, a transversemember connected to the last named parallel member forwardly ofits'rearward end and connected to the rearward end of the other of saidparallel members, of a downwardly and rearwardly extending bracketcarried by the rearward end of the rearwardly extended one of saidparallel members, a yokehaving a stem revolubly engaged in the bracket,a shaft journaled in the frame member above the bracket, detachableclutch connections between the shaft and the yoke, means for operatingthe detachable clutch connections, and a caster wheel mounted in theyoke.

2. In a power driven ap aratus, the combination with a frame iii udingtwo parallel members, one of said members projecting farther than theother, a uniting member connected to the last named parallel memberinwardly of its rojecting end, and connected to the end of the shorterparallel member, of a bracket carried by the pro-' jected end of thelonger parallel member, a yoke having a stem engaged in the said racket,a shaft journaled in the frame mem ber above said bracket, clutchconnections between said shaft and said yoke, means for operating thesaid clutch connections,- and a caster wheel mounted in said yoke. Intestimon whereof I afiix my signature,

. in presence 0 .two witnesses.
